Hello all! The other day I went to cock my RZ and noticed the lever wasn't 'cocking.' Upon further inspection I realized my mirror and light baffle were not rising. So, my issue is that upon completely cocking the RZs lever, the shutter is not cocking nor is the mirror being set. Haven't dropped it nor (hopefully) mishandled the body. I've tried different lenses and backs (Polaroid, 120) to see if that kicked it into gear somehow (newbie desperation moves!) to no avail. I do notice something by the mirror that I am unsure of being normal or not; two little arms within the body wall seem 'unhinged'. I attached some photos of the body field stripped and of two metal 'arms' that make me raise an eyebrow. Any input is greatly appreciated! Thanks all.
